Pulsar Little Big Board 8" System Boot disk & label - ChickenMan - 18-01-2021
Thanks to Emil for supply an IMD image of his original 8" disk and a copy of the disk label. Its from Pulsar Electronics Pty Ltd and titled CP/M 2.2 System & Source Code. The file CPM22.DOC list it as PULSAR L.B.B. BIOS Version 15 (LB15) and the READ.ME has it dated as 9th December, 1982.
Using the modified CPMTools with this will give you a directory of the disk :-

And to extract all the files to a pre-made folder called "files", use
cpmcp -f lbb_77dshd -T imd lbb_system_77dshd.imd 0:*.* files
The extracted SWEEP.COM was loaded onto a Microbee disk to test and it runs fine, an early version 1.2. All the text files (MAC, SCR, etc) all were extracted complete as well.
So in the Vintage Repository in the Pulsar\Disks folder we placed
lbb_system_disk_77dshd.imd
